On the heels of its ratings dominance during the Republican National Convention in Tampa, Fla., the Fox News Channel consistently trounced both its cable and broadcast competitors throughout Wednesday night’s presidential debate.

According to overnight numbers provided by Nielsen Media Research, FNC beat all broadcast and cable news networks yesterday evening. It averaged 10.4 million viewers from 9:00-10:30 p.m. EST, with nearly three million viewers in the key 25-54-year old demographic.

FNC nearly doubled CNN’s audience of 6 million viewers and more than doubled MSNBC’s viewership of 4.7 million. It also handily beat CBS, ABC and NBC during the actual debate.

It was a historic night for Fox News, giving the channel its highest-rated presidential debate ever. Also, FNC marked its third highest-rated prime time last night, with an average of 8.2 million viewers.
